Once we log into that account, we would like to transparently see all remote files we have some way of accessing (be it via telnet, FTP, rlogin
, NFS, or HTTP), all without having to ask the system administrator to install anything.
Particularly vulnerable services include rlogin
and rsh, which rely on "mutually trusting systems." See id.
Currently supported protocols include HTTP (Web), FTP, SMTP (email), rlogin
, telnet, finger, whois, and raw sockets.
One way to classify an Internet resource is whether it is a file, which you access by something like FTP (file transfer protocol); or a program, accessed by telnet, rlogin
They fixed their end of the program so that we could skip passwords and PIN numbers by doing an "rlogin
" instead of a Telnet.
